If the voltage at home is unstable, call the electric power bureau. The electric power bureau said it would ask an electrician to check the wiring of the property management.

The voltage at home is unstable. First find a property electrician to test whether the voltage of your external line is unstable or the voltage of your indoor line is unstable. The external circuit is managed by the property management or local power supply station, and the indoor circuit of your home is entirely your own property right, and you are responsible for it. If nobody calls 95598, she can help you, and then the mayor's hotline 12345, she will definitely help you solve the problem. Thank you. You pay indoors, but it seems that you don't need it outdoors.
